All gems are currently assuming Green quality gems from Northrend. 12 Str for Red Sockets and 6 Str/6 Hit for Yellow Sockets.

Also, I've left out Agi for two reasons. First, it's crit does not effect our spells. Second, there is agi present on exactly 23 pieces of plate in Northrend. It's a junk stat and should be avoided. If I had to rate it off of the top of my head I'd put it below haste... but that has no hard math behind it. But, since it's on so little plate, I think it's easily avoided anyway.

One question though:
According to EJ, 51/13/7-spec includes 5/5 Bladed Armor.
I don't see Armor playing any role in your scales. Do you consider it negligible or did you simply forget?

If I'm not all wrong about the calculations it should be somewhere along this line:

180 armor = 5 AP
36 armor = 1 AP
=>

Code:

Armor=0.028

OK, I admit its not going to turn a green item into a legendary one!
But I sometimes find the decisions between items a very close call and it might just be the final edge for a decision, or won't it? What do you think?

If I'm all wrong, please let me know so I can correct/delete this post.

I'd say go ahead and toss those AGI values in. And the Armor one as well if you use Bladed Armor. To be honest, I was kinda wondering why they didn't have Armor factored into their calculations.... and didn't feel like doing it myself ^_^

I would say that the armor could absolutely make a difference though. The agi? ... It seems so negligible and is on so little gear. But it may make a difference. I had forgotten it's effect on Armor though and thus on AP with Bladed Armor. I was originally looking at it strictly from the standpoint of Crit... Which if I understand correctly crit from AGI still does not effect spell criticals.
